java 伪静态的方法

1.jar包支持urlrewritefilter-4.0.3.jar  http://files.cnblogs.com/simpledev/urlrewritefilter-4.0.3.rar

2.在web.xml文件中加入：

<filter>
        <filter-name>UrlRewriteFilter</filter-name>
        <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
        <init-param>
          <param-name>logLevel</param-name>
          <param-value>WARN</param-value>
          </init-param>
    </filter>
    <filter-mapping>
        <filter-name>UrlRewriteFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

3.在项目的WEB-INF/文件夹下面加入：urlrewrite.xml

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN"
        "http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">

<!--

    Configuration file for UrlRewriteFilter
    http://www.tuckey.org/urlrewrite/

-->
<urlrewrite>

    <rule>
        <note>
            The rule means that requests to /test/status/ will be redirected to /rewrite-status
            the url will be rewritten.
        </note>
        <from>/test/status/</from>
        <to type="redirect">%{context-path}/rewrite-status</to>
    </rule>

    <outbound-rule>
        <note>
            The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)
            the url /rewrite-status will be rewritten to /test/status/.

            The above rule and this outbound-rule means that end users should never see the
            url /rewrite-status only /test/status/ both in thier location bar and in hyperlinks
            in your pages.
        </note>
        <from>/rewrite-status</from>
        <to>/test/status/</to>
    </outbound-rule>

    <rule>
        <from>/hudong.html</from>
        <to>/hudong.jsp</to>
    </rule>
    <rule>
        <from>/hudong/article/(\d+).html</from>
        <to>/careArticleAction?actionName=detail&amp;id=$1</to>
    </rule>
    <rule>
        <from>/hudong/article/(\d+)-(\d+).html</from>
        <to>/careArticleAction?actionName=detail&amp;id=$1&amp;pageId=$2</to>
    </rule>
    <rule>
        <from>/hudong/listArticle.html</from>
        <to>/careArticleAction?actionName=listArticle</to>
    </rule>
    <rule>
        <from>/hudong/listArticle-(\d+).html</from>
        <to>/careArticleAction?actionName=listArticle&amp;pageId=$1</to>
    </rule>
</urlrewrite>

注意：变量用$1,$2,$3等来取代，数字(\d+),字母(\w+)正则表达式来表达。
&符号一定要写成: &否则xml文件加载失败~!!!

. 　　匹配除换行符以外的任意字符
/w 　 匹配字母或数字或下划线或汉字
/s　　匹配任意的空白符
/d　　匹配数字
/b　　匹配单词的开始或结束
^　　匹配字符串的开始
$　　匹 配字符串的结束

项目启动之后：如访问http://localhost:8080/BNCAR2/rewrite-status 如果xml文件没有错误，会显示正常，否则会提示错误位置信息等。

以上链接伪静态代表的含义为：

访问http://localhost:8080/BNCAR2/hudong.html 代替http://localhost:8080/BNCAR2/hudong.jsp

访问http://localhost:8080/BNCAR2/hudong/article/100.html 代替http://localhost:8080/BNCAR2/careArticleAction?actionName=detail&id=100

访问http://localhost:8080/BNCAR2/hudong/article/100-1.html 代替http://localhost:8080/BNCAR2/careArticleAction?actionName=detail&id=100&pageId=1

访问http://localhost:8080/BNCAR2/hudong/listArticle.html 代替http://localhost:8080/BNCAR2/careArticleAction?actionName=listArticle
